Document Type and Number:
Japanese Patent JP2019088117
Kind Code:
A
Abstract:
To provide a gas-insulation switchgear having improved dielectric strength.SOLUTION: A gas-insulation switchgear according to the present invention comprises: a circuit breaker that breaks an electric current; an isolating switch that opens and closes a voltage; a ground switch; a main circuit conductor that electrically connects the circuit breaker, the isolating switch, and the ground switch; and an insulator 1 supporting the main circuit conductor. A non-liner resistance material 2 formed from a resistance material 7 of a nanometer size and a resistance material 8 of a micrometer size is added into the insulator 1.SELECTED DRAWING: Figure 1
